Stories as broadcast by gossip (5)
I believe the answer is:
sagas
'stories' is the definition.
(saga is a kind of story)
'as broadcast by gossip' is the wordplay.
'broadcast' indicates anagramming the letters.
'by' is a charade indicator (letters next to each other).
'gossip' becomes 'gas' (I've seen this before).
'as' anagrammed gives 'sa'.
'sa'+'gas'='SAGAS'
(Other definitions for sagas that I've seen before include "Heroic tales" , "Tales of heroes" , "Long involved stories" , "Myths" .)
